6.2 Connection Points
The controller cables are designed to connect to the following components:
- Assist Magnetic Point (3Pin): For pedal assist sensor.
- Throttle Handle (3Pin): For speed control.
- Power-off Brake (2Pin)*2: For brake levers with power cut-off function.
- Phase Wire: Connects to the motor's phase wires.
- Hall Wire: Connects to the motor's Hall effect sensor wires.
- Instrument (5Pin): For connecting to the e-bike display (ensure JN compatibility).
- Power Wire: Connects to the battery (DC36V/48V).
- Light (2Pin): For connecting e-bike lights.
Ensure each connection is firm and correctly matched according to the diagram and component labels. Incorrect connections can lead to system malfunction or damage.
7. Operation
Once the controller is correctly installed and all connections are secure, you can begin operating your e-bike system.
- Power On: Turn on your e-bike's battery and display. The controller will initialize.
- Speed Control: Use the throttle handle (Speed setting: 1.1-4.2V) to control the motor's speed.
- Braking: The controller supports low-level brake input, which will cut off motor power when the brakes are applied.
- Pedal Assist: If an assist magnetic point sensor is installed, the controller will provide motor assistance based on your pedaling.
Always operate your e-bike safely and in accordance with local regulations.
